Rochester, Minnesota - Lung cancer screening is used to detect the presence of lung cancer in otherwise healthy people with a high risk of lung cancer. The goal of lung cancer screening is to detect lung cancer at an early stage - when it's more likely to be cured.

Lung cancer is the leading cause of cancer deaths in the U.S., according to the American Cancer Society. Lung cancer claims more lives each year than colon, breast and prostate cancers combined. Although the disease can occur in people who have never smoked, people who smoke or have smoked have the greatest risk of lung cancer.

By the time lung cancer signs and symptoms develop, the cancer is usually too advanced for curative treatment. Studies show lung cancer screening reduces the risk of dying of lung cancer.
